為最大限度節(jié)約循環(huán)水，化工二部重點將節(jié)水目標鎖定在水冷器上。7月份以來，部門組織人員利用專業(yè)儀器對190臺水冷器進行全面摸排，對每一臺水冷器的運行狀況進行“把脈問診”，在保證水冷器安全運行的條件下，科學優(yōu)化調(diào)整水冷器進水量，對每一臺水冷器流速進行調(diào)整，確定最佳閥門開度并做好標示，操作人員結合實際工況進行“卡邊調(diào)整、限流操作”，最大限度節(jié)約用水。經(jīng)過系列攻關和操作優(yōu)化，7月份以來，1號聚丙烯裝置循環(huán)水耗量同比下降了22.96%，3號聚丙烯裝置循環(huán)水耗量同比下降了18.56%。
